Worked on enhancing the stability and cross-chain data reliability of Solana price feeds within the pyth-crosschain repository. Focused on a critical bug fix involving FeedId anchor serialization, the developer addressed serialization and deserialization issues by switching to a byte array approach. This solution improved compatibility with Anchor’s idl-build feature, reducing integration errors for Solana deployments. Using Rust and smart contract development skills, the work ensured more reliable price update data handling for downstream consumers. Although the period involved no new features, the targeted fix laid a stronger foundation for future development and improved the robustness of Solana-based integrations.
